	depends on GENERIC_GPIO
	select USB_OTG_UTILS
	help
	  Provides simple GPIO VBUS sensing for controllers with an
	  internal transceiver via the usb_phy interface, and
	  optionally control of a D+ pullup GPIO as well as a VBUS
	  current limit regulator.

	select USB_OTG_UTILS
	help
	  If you say yes here you get support for the Philips ISP1301
	  USB-On-The-Go transceiver working with the OMAP OTG controller.
	  The ISP1301 is a full speed USB  transceiver which is used in
	  products including H2, H3, and H4 development boards for Texas
	  Instruments OMAP processors.

	  This driver can also be built as a module.  If so, the module
	  will be called isp1301_omap.

config USB_ULPI
	bool "Generic ULPI Transceiver Driver"
	depends on ARM
	select USB_OTG_UTILS
	help
	  Enable this to support ULPI connected USB OTG transceivers which
	  are likely found on embedded boards.

config USB_ULPI_VIEWPORT
	bool
	depends on USB_ULPI

	bool "OTG support for Legcay Qualcomm on-chip USB controller"
	depends on ARCH_MSM
	select USB_OTG_UTILS
	default USB_MSM_72K
	help
	  Enable this to support the USB OTG transceiver on MSM chips. It
	  handles PHY initialization, clock management, low power mode and
	  workarounds required after resetting the hardware. This driver is
	  required for even peripheral only or host only mode configuration.
	  Supports SRP and HNP when both gadget and Host are selected.

config MSM_OTG_ENABLE_A_WAIT_BCON_TIMEOUT
	bool "Enable A-device timeout for B-device connection"
	depends on USB_MSM_OTG_72K
	default n
	help
	   OTG specification allows A-device to turn off VBUS if B-device
	   fails to signal connect event before TA_WAIT_BCON (1.1 - 30 sec).
	   SRP detection is enabled and hardware is put into low power mode
	   upon this timeout.

	   If you say yes, VBUS will be turned off if B-device does not signal
	   connect in 30 sec. Otherwise VBUS is not turned off when Micro-A
	   cable is connected. But hardware is put into LPM. Say no if leakage
	   currents in your system are minimum.
